FORTNITE is freezing

Основная проблема здесь:

Hello Epic Games. I'm writing to you because of a technical issue that's been bothering me. I've recently purchased a new PC with an RTX 5090 and an AMD RYZEN 7 9800 X3D, along with 96 gigabytes of RAM. However, I've been experiencing game freezes. Every 10-20 seconds, the game freezes for 0.5 to 1 second. This has a significant impact on my gaming experience and enjoyment. I'm looking for a solution to this problem. I manually tried to solve the problem by optimizing windows and updating the processor and video card drivers to the latest versions. I also tried to restart the internet just in case and change the rendering method from directx11 to directx12 and other methods between all four options. Please help me and thank you for your response. I forgot to mention that the sound in other applications starts to freeze along with the game. The system sometimes freezes as well, as far as I can tell

I've already used all of this, but the problem remains
- The problem is not with the Internet ( as far as I understand )

By the way, my system freezes with fortnite, not just fortnite. That means my system freezes. fortnite is like a machine that destroys my PC
